I bought a 628 a while back. Wasn't impressed but decided not to return it as it did most of the things I needed it to. I recently bought a Pioneer VSX-1015-TX and I now want the 628 to change the surround modes when I change activity. Let say I want to watch TV, I'd like the Pio to switch to "TV Surround" and if I play games, switch to "Game Surrounds" and finally if I want to watch a DVD, it switches to "Auto Surround".

I know how to customize the activities but the pull down menu doesn't provide the appropriate functions. How do I go about it ?
